kunit: Use KUNIT_EXPECT_MEMEQ macro

2022-10-27T08:40:14+00:00

Use KUNIT_EXPECT_MEMEQ to compare memory blocks in replacement of the KUNIT_EXPECT_EQ macro. Therefor, the statement KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); is replaced by: KUNIT_EXPECT_MEMEQ(test, foo, bar, size); Signed-off-by: Maíra Canal Acked-by: Daniel Latypov Reviewed-by: David Gow Signed-off-by: Shuah Khan

drm: tests: Fix a buffer overflow in format_helper_test

2022-10-20T07:56:05+00:00

The xrgb2101010 format conversion test (unlike for other formats) does an endianness conversion on the results. However, it always converts TEST_BUF_SIZE 32-bit integers, which results in reading from (and writing to) more memory than in present in the result buffer. Instead, use the buffer size, divided by sizeof(u32). The issue could be reproduced with KASAN: ./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \ --kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \ --kconfig_add CONFIG_KASAN_KUNIT_TEST=y \ drm_format_helper_test.*xrgb2101010 Reported-by: Linux Kernel Functional Testing Fixes: 453114319699 ("drm/format-helper: Add KUnit tests for drm_fb_xrgb8888_to_xrgb2101010()") Signed-off-by: David Gow Reviewed-by: Maíra Canal Reviewed-by: Javier Martinez Canillas Reviewed-by: José Expósito Signed-off-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221019073239.3779180-1-davidgow@google.com

drm/tests: Change "igt_" prefix to "drm_test_"

2022-09-14T16:53:33+00:00

With the introduction of KUnit, IGT is no longer the only option to run the DRM unit tests, as the tests can be run through kunit-tool or on real hardware with CONFIG_KUNIT. Therefore, remove the "igt_" prefix from the tests and replace it with the "drm_test_" prefix, making the tests' names independent from the tool used.
